2004 Dodge Ram 2500 HD 4x4: Fifth-Wheel Air Bags and Bilstein Shocks
Towing a 30-foot fifth-wheel camper with a 2004 Dodge Ram 2500 HD 4x4 calls for two separate decisions: choosing shocks for suspension control and confirming that rear air-spring brackets will clear the hitch structure. A truck that sits level does not, by itself, establish that it has a factory suspension lift.
The towing setup behind the question
This regular-cab, long-bed Ram carries camping gear and firewood while towing a fifth wheel with a reported 900-pound hitch weight. The owner identifies the hitch as a B&M Companion and describes a main support below the bed near the frame rails. The concern is whether that support occupies space needed by an Air Lift kit. That is a bracket-clearance question, not something that can be settled from trailer length or hitch weight alone.
Evaluate Air Lift 57295 against the hitch brackets
Air Lift 57295 is the kit to investigate for this question, not a confirmed clearance solution. Its installation instructions are identified in manual MN-668, covering 57295, 57290, and 57297: http://www.airliftcompany.com/manuals/MN-668_57295_57290_57297.pdf. Compare the specified mounting locations with the actual hitch supports, frame attachments, and available space. Have the air-spring installer and hitch installer resolve any overlap before purchasing or drilling. Do not relocate brackets or alter hitch structure based on an assumed fit.
Choose shock length from the suspension, not its stance
Bilstein Heavy Duty shocks are the recommended direction for this towing use. The unanswered detail is whether the truck actually has a suspension modification that changes shock requirements. A level appearance can result from several conditions and is not a reliable way to select extended-length shocks. Identify any lift components, spacers, or replacement springs before choosing the application. If the truck retains its standard suspension configuration, use the corresponding standard-height application rather than ordering lifted-truck shocks simply because the front and rear appear level.
Keep load support and damping separate
Rear air springs supplement the existing suspension under load; shocks control suspension movement. New shocks should not be expected to restore loaded ride height, and air springs do not eliminate the need for sound shocks. Include the camper's actual loaded pin weight, passengers, hitch equipment, firewood, and camping supplies when assessing the truck's load. Supplemental air support does not increase the vehicle's rated payload, axle ratings, or towing limits. Weighing the travel-ready combination is more useful than relying only on the camper's stated hitch weight.

Frequently asked questions
Will Air Lift 57295 clear the Companion hitch support?
Clearance is not established. Compare the kit's MN-668 installation layout with the actual below-bed hitch supports before ordering.
Does the Offroad designation mean I need longer Bilstein shocks?
Not by itself. Establish whether the suspension is standard height or has actual lift components before selecting shock length.
Should I use air bags or shocks for this towing setup?
They address different needs. Air springs provide supplemental load support; Bilstein Heavy Duty shocks are the recommended direction for controlling suspension movement.
